Why do u think so.
First of all, the output above is not correct. After 3 iteration key-value
API strats to return empty value.
Every 5 seconds(iteration sleep time) repository.getAttributes("1").size()
is got called. Which makes an entry "touch" and the entry wont be expired
for as long as 10 seconds.
Expiry policy says:
An {@link ExpiryPolicy} that defines the expiry {@link Duration}
* of a Cache Entry based on when it was last touched. A touch includes
** creation, update or **access**.*
